一、安装Oracle 11G前环境搭建
本次实验是基于Linux（CentOS6.7_64）下搭建oracle 11g环境，这里选择CentOS安装oracle并不是最佳选择，可以根据需要选择不同的Linux发行版，如Oracle Linux、SuSE Linux、Red Hat、IBM AIX等。
VM或物理机的配置要求：
在实验环境安装oracle11g最少需要2G内存、2个cpu、2G交换分区、磁盘空间不低于20G。
生产环境中，要保证oracle的性能，建议最低配置为8G内存、4个cpu、8G交换分区，如果生产环境比较繁忙，则需要更高的配置。
二、安装Oracle 11G前准备工作
上传oracle11g安装包，解压
linux.x64_11gR2_database_1of2.zip
linux.x64_11gR2_database_2of2.zip
配置/etc/hosts文件，添加ip与主机名的解析
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 #eth0 10.11.12.88 hm创建oracle相关用户和组
[root@hm ~]# groupadd dba [root@hm ~]# groupadd oinstall [root@hm ~]# useradd -g oinstall -G dba -m oracle [root@hm ~]# id oracle uid=500(oracle) gid=501(oinstall) groups=501(oinstall),500(dba)创建oracle软件安装目录
[root@hm ~]# mkdir /u01/app/oracle -p [root@hm ~]# chown -R oracle. /u01/ [root@hm ~]# chmod 775 -R /u01/ [root@hm ~]# ls -ld /u01/ drwxr-xr-x. 3 oracle oinstall 4096 Oct 14 22:58 /u01/oracle用户环境变量设置，su进入oracle用户下，修改~/.bash_profile文件，添加以下内容
export TMP=/tmp export TMPDIR=$TMP export ORACLE_TERM=xterm export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/db export ORACLE_SID=orcl export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib:/usr/lib64 if [ $USER = "oracle" ];then if [ $SHELL = "/bin/ksh" ];then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi修改内核参数，打开/etc/sysctl.conf文件，添加以下参数，并修改/etc/security/limits.conf文件
kernel.shmmax = 68719476736 kernel.shmall = 4294967296 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 [root@hm ~]# sysctl -p net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 在/etc/security/limits.conf文件末尾添加如下内容 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 4096 oracle hard nofile 65536 并同时修改/etc/pam.d/login文件，添加以下内容 session required pam_limits.so安装oracle依赖的软件包
[root@hm ~]# yum install gcc gcc-c++ libaio glibc compat-libstdc++-33 elfutils-libelf-devel libaio-devel libgcc libstdc++ libstdc++-devel unixODBC unixODBC-devel glibc-common ksh make sysstat pdksh [root@hm ~]# yum install glibc-2.12-1.192.el6.i686 检查是否安装 [root@hm ~]# for i in gcc gcc-c++ libaio glibc compat-libstdc++-33 elfutils-libelf-devel libaio-devel libgcc libstdc++ libstdc++-devel unixODBC unixODBC-devel glibc-common ksh make sysstat pdksh;do rpm -q $i;done |
三、安装oracle11g软件
解压oracle11g软件包
[root@hm oracle]# unzip linux.x64_11gR2_database_1of2.zip
[root@hm oracle]# unzip linux.x64_11gR2_database_2of2.zip
[root@hm oracle]# chown -R oracle. database/ [root@hm oracle]# ls -l database/ total 36 drwxr-xr-x. 12 oracle oinstall 4096 Aug 17 2009 doc drwxr-xr-x. 4 oracle oinstall 4096 Aug 15 2009 install drwxrwxr-x. 2 oracle oinstall 4096 Aug 15 2009 response drwxr-xr-x. 2 oracle oinstall 4096 Aug 15 2009 rpm -rwxr-xr-x. 1 oracle oinstall 3226 Aug 15 2009 runInstaller drwxrwxr-x. 2 oracle oinstall 4096 Aug 15 2009 sshsetup drwxr-xr-x. 14 oracle oinstall 4096 Aug 15 2009 stage -rw-r--r--. 1 oracle oinstall 5402 Aug 18 2009 welcome.html以orcle用户登录图形界面安装oracle，也可以使用vnc远程安装。这里直接用Xshell远程调用linux图形界面进行安装
